The pie charts illustrate the proportion of electricity generation by fuel source in France for the years 1990 and 2010.
Overall, the usage of nuclear power constituted less than a quarter of the total sources in 1990, but it drastically rose to nearly three-quarters in 2010. Meanwhile, the usage of coal and oil for electricity generation dropped by almost half during this period. Natural gas consumption also saw a significant decline from 1990 to 2010.
In 2010, nuclear power accounted for 50% of electricity generation, compared to just 17% in 1990. The recent value of nuclear power is equivalent to the total percentage of natural gas, nuclear power, and oil combined in 1990. In both years, hydropower showed the lowest contribution, with 6% in 1990 and only 2% in 2010. The usage of coal and oil decreased significantly over the years, with both dropping to nearly 50% of their earlier values. In 1990, natural gas represented 28% of electricity production, but this figure plummeted to just 4% by 2010.
The pie charts highlight the significant fluctuations in the proportions of different sources contributing to electricity production over the two decades.
